Description

  TECHNICAL FIELD The present invention relates to a fitting for piping and the like used as means for attaching a piping for passing cables such as electric wires to a steel beam or a steel column of a building.

  Although a patent document cannot be shown as a mounting bracket for this type of pipe, a U-shaped clamp having a concave space continuous in a U-shape on the inner side and fitted to a mounting plate portion and fixed with a fastening bolt is provided. And a holding member for holding a mounting member such as a pipe, and a mounting bracket including a fastening bolt have been known for a long time.

  The above-described conventionally-known mounting bracket has a structure in which the holding member, which is composed of two members, a receiving member and a pressing member, is connected to each other by a fastening bolt on site with the mounting member such as a pipe interposed therebetween. Yes, for example, when the mounting member, such as a pipe, is sandwiched between the receiving member and the holding member, the holding member cannot be temporarily fixed to the U-shaped clamp. Therefore, there is a problem that workability is poor and it is difficult to work efficiently.

  The present invention proposes a fitting such as a pipe which can solve the conventional problems as described above, and the fitting such as a pipe according to the present invention has a relationship with an embodiment described later. For ease of understanding, the reference numerals used in the description of the embodiment are shown in parentheses, and have a concave space (4) that is continuous in a U-shape on the inside, and the mounting plate (5) has It consists of a U-shaped clamp (1) that is fitted and fixed with fixing bolts (6), a holding tool (2) that holds the mounting member (14) such as piping, and a fastening bolt (3). 1) includes a sub-plate portion (8) facing the main plate portion (7) through which the fixing bolt (6) is screwed, and a connecting plate portion (7) connecting the main plate portion (7) and the sub-plate portion (8). 9), a connecting hole (11) is provided in at least one of the plate portions, and the holding member (2) includes a holding portion (15, 16) for holding the mounting member (14). Vice 2 The connecting hole, which is formed of two holding members (12, 13), and which protrudes outward away from each other at front ends of the main and sub holding members (12, 13) in front of the holding portions (15, 16). Locking pieces (18, 19) to be inserted into (11) are provided, and the auxiliary holding member (13) is provided with a retaining projection (24) at an end behind the holding section (16). The main holding member (12) is provided with a bendable extension plate portion (22) extending from an end behind the holding portion (15) to the side of the sub-holding member (13). An engaging hole (23) through which a portion of the sub-pinching member (13) adjacent to the retaining protrusion (24) penetrates is formed in the extension plate portion (22). It is provided in the shape of a long hole along the direction, between the holding portion (15) of the main holding member (12) and the extension plate portion (22), and the holding portion (16) of the sub-holding member (13) One of the space between the holding member (12, 13) and the retaining projection (24) has a long hole (20) long in the length direction of the holding member (12, 13). The other end is provided with a through-screw hole (21), and the fastening bolt (3) is threaded through the through-screw hole (21) at the tip end thereof that has passed through the long hole (20). It has a configuration.

  In the above configuration, the holding device including the two main and sub holding members is integrated by the fastening bolts, the leading ends of the one holding member passing through the long holes being screwed through the through screw holes of the other holding member. In addition, since the portion of the sub-holding member adjacent to the extension for retaining is penetrated through the engagement hole of the extension plate portion of the main holding member, the two main and sub-holding members are connected to the fastening bolt. It is in a state where it cannot rotate relatively around. In this state, if the fastening bolt is unscrewed within a range that does not fall out of the through screw hole, the existence of the elongated hole through which the fastening bolt penetrates and the elongated engagement hole of the extension plate portion is present. The main and sub two holding members can be relatively opened so that the locking pieces at the distal ends are separated from each other. By thus increasing the distance between the leading ends of the two main and sub-holding members, it is possible to relatively insert the mounting member (such as a pipe) between the leading ends of the two holding members and between the holding portions. Of course, when there is little spread between the tips of the two main and sub clamping members, the mounting member can be inserted from the lateral side between the clamping portions of both clamping members.

  Thereafter, the leading ends of the two main and sub clamping members are sandwiched between the fingertips, and the engaging pieces at the distal ends of the two clamping members are brought closer to each other. ) Can be inserted into the connection hole of the U-shaped clamp previously attached to the steel mold or the like to be attached. From this state, the rear ends of the two holding members are sandwiched between the fingertips, and the distal ends of the two holding members are widened with the mounting member (such as a pipe) sandwiched between the two holding members as a fulcrum, and the leading ends of the two holding members are locked. When the piece has entered the back side of the connection hole of the U-shaped clamp, the extension plate portion of the main holding member is set rearward with the inside of the retaining protrusion at the rear end of the sub-holding member bent. Fold outward. As a result, the posture of both holding members is fixed with respect to the mounting member (such as piping), and the holding tool that holds the mounting member (such as piping) is temporarily fixed to the U-shaped clamp. Can be separated.

  If the holding member holding the mounting member (such as piping) is temporarily fixed to the U-shaped clamp as described above, the position of the mounting member (such as piping) in the longitudinal direction of the holding member is corrected, and then the fastening is performed. The bolts are screwed in to forcibly move the rear ends of the holding members extending rearward from the mounting member (piping, etc.) toward each other to enter the back side of the connection hole of the U-shaped clamp. By forcibly opening the front end sides of both holding members provided with the locking pieces and pressing the holding members against the inner peripheral surface of the connection hole, the holding member holding the mounting member (such as a pipe) at a predetermined position is used. Can be completely fixed to the U-shaped clamp. The extension plate portion of the main holding member bent backward and outward for temporary fixing may be left as it is, but may be returned to its original position if it obstructs the extension. When it becomes necessary to remove the attached mounting member (piping or the like), if the extension plate portion is in a bent state, the fastening bolt is screwed with the extension plate portion returned to its original position. Then, the fastening of the rear ends of the two holding members is released, and the front ends of the two holding members are pinched by the fingertips so that the two locking pieces are moved closer to each other. The piece may be pulled out from the connection hole of the U-shaped clamp, and the holding tool may be removed from the U-shaped clamp.

  As described above, according to the mounting bracket such as the pipe of the present invention, not only the main and sub two holding members constituting the holding device are integrated by the fastening bolt, but also the two holding members are around the fastening bolt. Since there is no relative rotation, the connecting operation to the U-shaped clamp can be performed easily and efficiently. In addition, when the mounting member (piping, etc.) is sandwiched between the holding portions of the two main and sub-holding members, the space between the two holding members can be greatly increased. In addition to the insertion, it is also possible to fit the middle part of the mounting member (such as piping) into the holding tool. Then, before the fastening bolt is screwed in, the holding member holding the mounting member (such as piping) can be easily connected to the U-shaped clamp and temporarily fixed, so that the workability is remarkably improved. After the mounting position of the mounting member (such as piping) is corrected in the temporarily fixed state, the mounting member (such as piping) can be securely fixed to the U-shaped clamp simply by screwing the fastening bolt.

  The elongated hole (20) is provided in the main holding member (12), and the through-screw hole (21) is provided in the sub-holding member (13), whereby the elongated hole ( The direction in which the fastening bolt (3) protrudes from the head side from (20) and the direction in which the extension plate (22) provided on the main holding member (12) extends are opposite to each other. There is no possibility of interference, and the extension plate portion can be easily configured.

  Further, the connecting hole (11) of the U-shaped clamp (1) is formed in a circular shape, and from the holding portions (15, 16) of the main and sub two holding members (12, 13) to the locking pieces (18, 19). Can be formed in an arc-shaped cross section which is fitted into the circular connection hole (11) so as to be relatively rotatable. According to this configuration, while increasing the strength of the distal end side of both the holding members, the holding tool is rotated with respect to the connection hole of the U-shaped clamp, and the angle of the mounting member (such as piping) held by the holding tool is adjusted. Can be adjusted. Further, in addition to this configuration, the holding portions (15, 16) of the main and sub two holding members (12, 13) are formed in an arc shape that protrudes outward, and the holding portions (15) having the arc shape are formed. The left and right sides of the strip plate forming the portion having the long hole (20), and the strip plate material forming the portion having the arc-shaped holding portion (16) and the through screw hole (21). By forming bending pieces for reinforcement (25, 26) on the left and right sides of the holding member, the overall strength of both holding members can be sufficiently increased.

  An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the mounting bracket of the present invention includes a U-shaped clamp 1, a clamp 2, and a fastening bolt 3. As shown in FIGS. 1 and 2, the U-shaped clamp 1 has a concave space 4 which is continuous in a U-shape on the inside, and is fitted to a mounting plate portion 5 such as an edge portion of a steel frame and fixed with a fixing bolt 6. A sub-plate portion 8 facing the main plate portion 7 through which the fixing bolt 6 is screwed and a connecting plate portion 9 connecting the main plate portion 7 and the sub-plate portion 8. Circular connection holes 10 and 11 having the same diameter are provided in the center of the connection plate 8 and the connection plate 9.

  As shown in FIGS. 1 and 3 to 12, the holding device 2 includes a main holding member 12 and a sub-holding member 13 each formed from one band-shaped plate material. At intermediate positions in the longitudinal direction of the holding members 12 and 13, arc-shaped holding portions 15 and 16, which can be externally fitted from both sides to an electric conduit 14 having a circular cross section as an attachment member, are symmetrically formed. Locking pieces 18 and 19 are provided at the tip portions of the holding members 12 and 13 so as to be bent outward in a direction away from each other. The distal end portions 12a, 13a between the holding portions 15, 16 of the holding members 12, 13 and the locking pieces 18, 19 have substantially the same diameter as the inner peripheral edges of the connection holes 10, 11 of the U-shaped clamp 1. Is formed into an arc-shaped cross section projecting outward.

  More specifically, the rear portion from the holding portions 15 and 16 of the main and sub holding members 12 and 13 to the rear end (the end portion of the holding members 13 and 14 on the opposite side to the front end portions with the locking pieces 18 and 19). The end portions 12b and 13b are plate-shaped parallel to the length direction of the holding members 12 and 13, and the rear end portion 12b of the main holding member 12 has a lengthwise direction that corresponds to the length direction of the main holding member 12. In the rear end portion 13b of the sub-clamping member 13, there is provided a through screw hole 21 formed by forming a female screw groove on the inner surface of the burring surrounding wall protruding outward.

  From the rear end of the rear end portion 12b of the main holding member 12, a bendable extension plate portion formed by bending the extension strip of the rear end portion 12b to the side where the sub-holding member 13 is located. The extension plate portion 22 is provided with an engagement hole 23 in a long hole shape along the extension direction of the extension plate portion 22. In the illustrated structure, the extension plate portion 22 is curved in a direction closer to the locking piece 18 at the distal end of the main holding member 12 toward the distal end side. From a rear end of the rear end portion 13b of the sub-clamping member 13, a retaining protrusion 24 having a width substantially equal to the width of the rear end portion 13b is continuously provided via a small-width neck portion 13c. The whole of the rear end portion 13b, the narrow neck portion 13c, and the protrusion 24 for retaining are located on a flat surface parallel to the length direction of the sub-clamping member 13. The width of the small-width neck portion 13c is slightly smaller than the width of the engagement hole 23 provided in the extension plate portion 22 of the main holding member 12. Note that the band portion forming the holding portion 15 and the rear end portion 12b of the main holding member 12 and the band portion forming the holding portion 16 and the rear end portion 13b of the sub-holding member 13 are provided. Outwardly extending bent sides 25 and 26 that are continuous over the entire length of the left and right sides are integrally formed.

  In the holding device 2 configured as described above, as shown in FIG. 1, the main holding member 12 and the sub holding member 13 are connected and integrated by the fastening bolt 3. That is, first, the main holding member 12 and the sub-holding member 13 are tilted relative to each other by 90 degrees, and the width direction of the retaining protrusion 24 of the sub-holding member 13 is changed by the engagement of the extension plate portion 22 of the main holding member 12. After inserting the retaining projection 24 into the engagement hole 23 from the inside of the extension plate portion 22 in a direction parallel to the length direction of the hole 23, the main clamping member 12 and the sub-clamping member 13 are relatively moved. And the small-width neck portion 13c adjacent to the retaining protrusion 24 is returned in the width direction of the engagement hole 23 so that the retaining protrusion 24 projects outside the engagement hole 23. I do. In this state, the fastening bolt 3 is inserted into the long hole 20 of the main holding member 12 from the outside, and the tip end of the fastening bolt 3 is screwed and penetrated into the through screw hole 21 of the sub-holding member 13. At this time, the screwing depth of the fastening bolt 3 with respect to the through screw hole 21 is minimized as shown in the figure, and the main holding member 12 moves the fastening bolt 3 in the axial movement and the tilting movement within a sufficient range. Be prepared to do it. The axial movement and the tilting movement of the fastening bolt 3 of the main holding member 12 are caused by the small-width neck portion 13c of the sub-holding member 13 being engaged in the engagement hole 23 of the extension plate portion 22 of the main holding member 12. Since it is limited to the range which can be carried out, the holding parts 15 and 16 of the both holding members 12 and 13 do not move relatively around the fastening bolt 3 and are always kept in a facing state.

  A method of using the mounting bracket of the present invention comprising the clamp 2 and the U-shaped clamp 1 assembled as described above will be described with reference to FIGS. 13 to 18. First, the assembly as described above will be described. As shown in FIG. 13, the holding tool 2 is relatively opened so that the leading ends of the holding members 12, 13 with the locking pieces 18, 19 open. In this state, the holding member 2 is relatively fitted into the conduit tube 14 as a mounting member from the side, and the holding members 12 and 13 are engaged with the locking pieces 18 and 19 at the distal ends thereof as shown by phantom lines. The electric conduit 14 is held between the holding parts 15 and 16 of the holding members 12 and 13 so as to be close to each other.

  On the other hand, the U-shaped clamp 1 is fitted to a mounting plate portion 5 such as a steel frame to which the conduit 14 is to be mounted, and the fixing bolt 6 is screwed in so as to be mounted between the tip of the fixing bolt 6 and the sub-plate portion 8. Since the plate portion 5 is fixed to the mounting plate portion 5 by being clamped, as shown in FIG. , 19 are inserted into the connecting holes 11 of the U-shaped clamp 1, and the hand for gripping the holding tool 2 is moved to the rear end side of the holding tool 2, and the rear end sides of the main and sub holding members 12, 13 are moved. Are held close to each other. As a result, as shown in FIG. 15, the two holding members 12, 13 open so that the locking pieces 18, 19 at the distal ends are separated from each other with the conduit tube 14 as a fulcrum, and the locking pieces 18, 19 are pushed together. The clamp 1 enters the inside of the connecting plate 9 on both sides in the diameter direction of the connecting hole 11.

  As described above, when the holding members 12, 13 are closed around the conduit 14 as a fulcrum, and the locking pieces 18, 19 at the distal ends are adjacent to each other, the locking pieces 18, 19 are used. Are formed in the connecting holes 10 and 11 of the U-shaped clamp 1 in such a size and shape that they can be linearly inserted along the axial direction of the connecting holes 10 and 11. It is also possible to insert the locking pieces 18 and 19 into the connecting holes 10 and 11 sequentially from one side while moving the holding tool 2 up and down or left and right. The engagement effect can be enhanced by increasing the height.

  As shown in FIG. 15, if the locking pieces 18, 19 at the distal ends of the sandwiching members 12, 13 enter the inside of the connecting plate 9 on both sides in the diameter direction of the connecting hole 11 of the U-shaped clamp 1, As shown by an imaginary line in FIG. 15, the extension plate portion 22 of the main holding member 12 is bent rearward so as to be bent outside the narrow neck portion 13c of the sub holding member 13. As a result, the bent extension plate portion 22 prevents the holding member 2 from being deformed so that the rear ends of the holding members 12 and 13 are opened, so that the holding member 2 enters the inside of the connection hole 11 of the U-shaped clamp 1. There is no danger that the locking pieces 18 and 19 move closer to each other and the holder 2 comes off the connecting hole 11 of the U-shaped clamp 1. That is, the conduit tube 14 is temporarily fixed to the U-shaped clamp 1 (mounting plate portion 5) while being clamped by the clamping device 2. In this way, the conduit tube 14 temporarily fixed to the target position is moved in the length direction between the holding portions 15 and 16 of the holding members 12 and 13 in the holding device 2, and the U-shape is held together with the holding device 2. Since it is possible to rotate around the connecting hole 11 of the clamp 1, another portion of the conduit 14 in the longitudinal direction is changed to another portion by using another holding tool 2 and the U-shaped clamp 1. Can be temporarily fixed to the mounting plate portion 5.

  As described above, when the conduit tube 14 is erected at a predetermined position using the clamp 2 and the U-shaped clamp 1 in a temporarily fixed state, the fastening bolt 3 of each clamp 2 is finally screwed in, and the figure is drawn. As shown in FIG. 16, by strongly pressing the rear end side portion 12b of the main holding member 12 against the rear end side portion 13b of the sub holding member 13, the holding portions 15, 16 of the two holding members 12, 13 are connected to the conduit tube 14. At the same time, the outer peripheral surfaces of the distal end portions 12a, 13a adjacent to the locking pieces 18, 19 of the sandwiching members 12, 13 are pressed against the inner peripheral surface of the connection hole 11 of the U-shaped clamp 1, As shown in FIG. 17, the conduit tube 14 is fixed to the mounting plate portion 5 without rattling. Although the extension plate portion 22 of the main holding member 12 bent outward may be left as it is, after the final fastening operation by the fastening bolt 3 is completed, as shown by a virtual line in FIG. In addition, the extension plate portion 22 that has been bent outward is bent back to the original position, and the clothes and the like of a worker passing by the side of the conduit tube 14 are bent outward and project. It is also possible to prevent an accident that is caught on the part 22.

  In the above usage example, as shown in FIG. 17, the holding member 2 is coupled to the horizontally oriented connecting hole 11 of the U-shaped clamp 1 fitted and fixed to the side of the horizontally oriented mounting plate portion 5. However, as shown in FIG. 18, when the U-shaped clamp 1 is fitted and fixed to the upper side (or the lower side) of the vertically oriented mounting plate portion 5, the U-shaped clamp 1 is oriented horizontally. It is also possible to use the holding tool 2 by connecting it to the connecting hole 10. Further, a long hole 20 through which the fastening bolt 3 penetrates is provided in the rear end portion 13b of the auxiliary holding member 13, and a through screw hole 21 is provided in the rear end portion 12b of the main holding member 12, so that the fastening bolt 3 is turned in the opposite direction. It is also possible to adopt a structure used for

  The fittings such as pipes of the present invention can be used as means for attaching pipes for passing cables such as electric wires to steel beams or columns of buildings.
